Simplify the expression as follows;
[tex]\begin{gathered} 10x-5=-45 \\ \text{Add 5 to both sides of the equation} \\ 10x-5+5=-45+5 \\ 10x=-40 \\ \text{Divide both sides by 10} \\ \frac{10x}{10}=\frac{-40}{10} \\ x=-4 \end{gathered}[/tex]
Option B is the correct answer.
The statement is true when x = -4
